Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
Embodiment：As shown in Figure 1-Figure 3, a kind of gas spring assembly with auto-lock function of the present invention, positioned at hatch door top,
The eyebrow beam 1 of mouth frame and the junction of auxiliary frame 2；Including：
Gas spring 3, is symmetrical arranged side by side by two, and one end is connected on the hatch door mouthful auxiliary frame 2 of frame, is hinged with auxiliary frame 2, another
End connection self-locking device；
Bearing 5, one end is connected on self-locking device, and the other end is affixed with hatch door mouthful frame eyebrow beam 1, play fixed supporting role；
Pull bar 10, one end is connected on self-locking device, other end connection hatch door；
Self-locking device, difference connects bearing 5, the gentle spring 3 of pull bar 10, thereon with the locking member 6 and gear for cooperating
Block 12, when hatch door is opened in final state, the block 12 is locked with the locking member 6 being connected on bearing 5.
As Figure 4-Figure 7, the self-locking device includes：
Shown, connecting crank 4 is triangular frame structure, and one jiao of end is connected on two gas springs, and the angle end carries two points
Not Lian Jie gas spring 3 adapter sleeve hole, be sleeved on gas spring 3；One jiao of end cylinder lever connecting rod 10, the angle end is with connection bearing pin 13
Two connecting holes, between pull bar 10 is placed in two connecting holes, connected by bearing pin 13；Another angle end connection rotating shaft 7, the angle end is with company
Switch through the mounting hole of axle 7, bearing 5 is nested with the rotating shaft 7, positioned at the outside of connecting crank 4, near the connecting crank 4 at the end of rotating shaft 7
Outward flange carries block 12；Connecting crank 4 keeps contacting with locking member 6 in unlocked timing instant, and connecting crank 4 is to locking member
6 opposition F1 and both contact points are more than 30 ° with sharp angle α folded by the line of centres of lock shaft 9, it is ensured that hatch door opening or
Stuck situation will not occur in closing process.
As shown in Fig. 2, Fig. 7, locking member 6 on lock shaft 9, between connecting crank 4 and bearing 5, is opening cabin
During 7 rotation around the shaft of door connecting crank 4, locking member 6 is slided along the surface of connecting crank 4, when hatch door is opened in final state,
Locking member 6 is just locked with the block 12 on connecting crank 4, realizes self-locking.In the locked state, the termination of locking member 6 with
Maximal clearance between the block 12 of connecting crank 4 is 1mm -2mm；When there is resilience in gas spring 3, locking member 6 and connecting crank
4 block 12 is contacted, directed force F 2 and both contact points and the angle β of lock shaft 9 line of centres of the connecting crank 4 to locking member 6
Less than 5 °, as shown in fig. 6, force direction is on the lower side for both lines above-mentioned, so ensure the security of self-locking.
As shown in fig. 7, the locking member 6 is made up of homonymy on axle sleeve with two symmetrical stopper blocks, the stopper block end
Head coordinates for the block 12 in arc transition, with connecting crank 4, convenient unblock.
As Figure 4-Figure 7, the block 12 on the connecting crank 4 is two, is symmetrically set in the edge side of connecting crank 4
Put, in the locked condition, the block 12 is in contact with stopper block termination, mutually stop, form self-locking.
Torsion spring 11 is also set with the lock shaft 9, release lever 8 is fixedly mounted on lock shaft 9, the two ends of torsion spring 11 connect respectively
Bearing 5 and release lever 8 are connect, and torsion spring 11 makes release lever 8 have the trend for rotating down.Handle 8 is pulled during unblock, lock is driven
Tight part 6 is rotated, and locking member 6 is bypassed the position of block 12 of connecting crank 4, releases locking.
Operation principle of the invention：
When hatch door is opened, gas spring 3 extends, and gas spring 3 promotes connecting crank 47 to rotate around the shaft, and I is moved in such as Fig. 4
It is shown, enable connecting crank 4 to drive locking member 6 to be slided along the surface of connecting crank 4, this motion makes locking member 6 drive lock
Axle 7 is rotated, and II is moved as shown in Figure 4；When hatch door is in opens final position, locking member 6 just bypasses the gear of connecting crank 4
The position of block 12, completes locking, as shown in Figure 5.
When needing to unlock, release lever 8 (as shown in Fig. 5 motions III) must be rotated up, release lever 8 drives lock shaft
9 rotate, and lock shaft 9 drives locking member 6 to be turned out (as shown in Fig. 5 motions IV), makes locking
Part 6 can bypass the position of block 12 of connecting crank 4, unlock, and can now close hatch door.
